How do I implement async rules in VeeValidate with Vue 3?

To implement async rules in VeeValidate with Vue 3, you can use the defineRule function to create custom async validation rules.

Can you show me an example of an async rule?

Sure! Here's a simple example:

import { defineRule } from 'vee-validate';

defineRule('asyncEmail', async (value) => {
  const response = await fetch(`/api/validate-email?email=${value}`);
  const data = await response.json();
  return data.isValid ? true : 'Email is already taken.';
});

What if I want to validate multiple fields asynchronously?

You can create multiple async rules and apply them to different fields. Just ensure each rule handles its own validation logic.
